Open the graphsheet you want to select datapoints from. Use the classic script windows and open the screenreaderdataexport.ogs file. Enter the number of data points you wish in the last line (default is 60). Highlight the entire script and hit enter. The Origin should switch back to the graph with the screenreader tool active. To select data points use the mouse or arrow keys to highlight the point and double click or hit enter. When the desired number of points is reached the data is exported to a new worksheet 'TEMPOR'. If you run the script again and select new points the data in the TEMPOR worksheet is replaced. NOTE: worksheet is not wiped every time the script is run so if you select fewer datapoints the second time there will be datapoints in the worksheet from the previous run. Also this script was made using Origin 8. I do not know if it will work as is in previous versions. To get it to work in earlier versions I believe you will have to edit the worksheet creation and range assignment lines of the code.
